It gave me a question.If I define beats of first white key as quarter notes,second white key
must beat eighth.when first and seccond keys were pressed at same time,quarter notes and
eighth notes notes on beat would sound at same time.but the original rhythmicon is monophonic
isn't it?

O_O_O_O_ (second white key)
O___O___ (first white key)

How How does Rhythmicon work when these tow keys are pressed at once.
either one of the two sounds?

but I know,Theremin's third Rhythmicon seems to be able to make chourd!

I have a another question too.
Can player change fundamental and tempo individually?
If one of them were changed,another would be also changed?
